To all whom t may concern:

Be it known that I, EDWARD L DELANY,

residing atV and whose postoiiioe address is S28 Kent avenue, in the city of N ew York, in the county of Kings and State of New -York, have invented certain new and'useful Improvements in Float-Valves; and do hereby declare the following to be a full7 clear, and exact description of the invention, such as willvenable' others skilled in;

the art to which it appertains to make and use the same.

My present invention contemplates improving the valve mechanism ot' `ilush tanks equipped with float valves. v

One of the objects 'of the invention is to provide an 'improved washer and another object is to provide improved means for securing the washer to the valve parts.

lin the accompanying drawing Figure 1 is a vertical sectional view show-ing a valve mechanism embodying my invention. Fig. 2 is a detail. Fig. 3 is a fragmentary section showing the position of the washer when the valve is seated..

Referring to the drawing l designates a casing adapted for iush tanks and provided with an overflow tube 2. On this tube 1 have shown mounted a lateral arm 8 slotted at its outer end to form a guide for the operating rod 4 by which the valve is unse'ated. This rod is shown extending downward through the lioat 5 and valve 6 into the Spud 7 whereit passes through a guide 8. The lioat 5 is secured to rod' l as at 9 and carries valve 6 in its vertical movement.

The valve elements comprises` a Heat and a cylinder lO. The float isshown formed with an interiorly threaded tubular portion 12 to "receive the valve body or threaded cylinder 10, both the tubular 'part 12 and the cylinder being open at their upper ends. The cylinder is closed at its lower end eX- cept vfor a vent 13. Surrounding the tubular portion 12 the float is shown formed with a downward projecting bead 14. At

its. lower or closed endl the y'cylinder is formed with a flange 15 curved outward and upward and termed with a slot 1 6 at any point thereof as shownvv in Fig.. 2.

The washer 1'? is of peculiar formation. )it is preferably a rubber ring bent back upon itselic as at 18 to form. the horizontal part 19 and the depending part 20 which entends beneath the Harige lo and contacts relatively t wear by reason of the ratentea one ai, taie.

with the latter and valve 'seat 2l. At the inner end of the horizontal part 19 the washer is formed with a shoulder 22 the upper end of whichT is held between the bead 1-1 on thetloat and the wall of cylinder 107 while the lower end of said shoulder is rabbeted to enter, and conform to, the flange 15.

In Letters Patent No. 1,077,457' issued to me November 4, 1913, I have shown and described a washer having for its :features a shoulder securely held betweenl two valve parts and formed with laterally and downwardly projecting tapering eXtreInities whose combined formation .corresponds to that of the valve seat.- The construction referred to is efficient in that it provides effective means for holding the washer at a part thereof not touched by the ivatenwhile of the two tapering extremities always immersed while the other isy immersed only when the-valve is open.

The present invention, while maintaining this idea, provides a stronger washer at the bend 18 and is characterized by a spring action which materially aids its efficiency. Furthermore there is an increased area of the washer in contact that of the patent referred to. It will he noted that in the form of embodiment illustrated thcfunder face of the horizontal part 19 of the washer is curved as at 23 and that this curvature corresponds' they have to bend the part 20 of the washer.

into corresponding formation" and overcome its spring actlon which tends to mamtam only one is it in the disposition shown in Fig. I where the valve 1s open.

As the valve unseats and the part 20 eX- pands under its tension 'it draws Water through port 16 into the channel 24 which latter is created by the expansion, When the valve -drops forcibly to its, seat under the suction in the spud 7 the water containedin the channel or cavity 24 acts tem` porarily an a cushion and passes out through slot 16, thus saving the washer from undue forcible impact.
